Description from storeThis extension that allows you to quickly look up definitions of words and phrases in a clean inline box. The definitions come from Wiktionary, but have been preprocessed to reduce formatting and provide faster lookup. Hold a modifier key (Alt on Windows, Command on Mac, Ctrl on Linux) and double-click or select any word to look it up - an inline box will open to the dictionary entry of that word, usually including examples, audio pronunciation and synonyms.
You can also lookup manually-entered queries using a shortcut which displays a small query form.
NOTES:
1. After installing, pages already open will not work for looking up - just refresh them and it'll be solved.
2. The Chrome Extensions Gallery pages don't allow lookup (or any on-page extensions) for security reasons.
3. This extension does not add a toolbar icon.

Latest reviews

(2019-12-26) Sean Gilbertson: This is exactly what I wanted -- an extension that will show me _multiple_ definitions when I double-click on words on a web page. Works great on my Mac! Thank you for making this, Max!

(2018-09-02) Era Javukh: It's not working. It never did for the past year. I click on a word and nothing shows up.

(2017-09-06) David Apricot: Fantastic. It uses sentences, synonyms, pronunciations, and great definitions! Get it.

(2017-08-24) Luca Gentile: It uses a lot of memory

(2017-06-20) Kate Marsh: Have you thought about porting this over to Edge? I have for myself but restarting the browser results in it breaking because it isn't signed. I think Edge users can benefit from this as there currently is no extension of its kind available

(2017-03-25) Santiago Restrepo: je ne sais pas comment l'utilisser

(2017-01-19) Mobin Skaria: Best Dictionary of all time.

(2017-01-15) 黄圣达: 如果能保存翻译记录就好了..

(2016-11-06) Markus Varis: Does only seem to pull English definitions from Wiktionary. Does not work for other languages. This is counter intuitive because Wiktionary contains a lot of information about a lot of languages.

(2016-11-04) min haj: this is certainly cool but need improvement about voice output

(2016-05-03) Tarek Ahmed: I realized that this extension interferes with the proper loading of some PDF files and causes them not to load at all.

(2016-04-13) Jin Wang: This app interferes with pdf viewer in chrome! Got to fix this bug.

(2015-06-07) dronem10: No longer will I have to copy-paste words onto a separate page. Just alt-click and definition appears. Perfect.

(2015-05-17) Zii Heem: Alt + Mouse click, easy, simple. Like it

(2015-04-20) Zaid Siddiqui: It' great, but I wish there was an option so the popup would just instantly go away instead of fade away.

(2015-04-03) Ahmad mazahrah: it is the best for chrome

(2015-04-01) Phillip Guerra: had to refresh the page so it would work!!!!
